Inverter control cabinet of BD381 series specially for pumping units is designed by Fuling Company according to the actual production need of oil fields. The power range is between 15 to 75Kw. It is equipped with energy feedback as an organic whole, as well as dust prevention, waterproof function and anti-slide function; high torque outputs in low speed. Reasonable optimization are implemented by research personnel in terms of performance, reliability and stability, which makes its energy-saving and cost-reducing advantage and other superiority presented to users more evidently during the use process, thus making it the first choice in oil field power drive industry.

Product features

Integrate the inverter and energy feedback as an organic whole, and send back the energy of pumping units in generating state to the power grid, which makes the energy-saving more obvious.The control mode that making the generating energy and output frequency correspondent are used through the control over output frequency of the inverter.Meet the standard that overvoltage protection will not occur during electricity generation of pumping units. Meanwhile, it is applicable to be used by oil fields of different types.Take full consideration of dust prevention, waterproof function and anti-slide function.Volume of control cabinet is reduced. Cost is low and repair is convenient. The interference to power grid is reduced.Internally installed heating units. It keeps running even in low temperature.The electricity meter can be installed inside. The energy-saving is evident.Industrial design of inverter ensures the continuity of production.Power range:15kW~75kW
